The questionable Question Mark (?) in C#

This under-rated character can make writing C#(or Perl) codes easier and simple.

It can either be a comparator or a null-conditional if-else statement, in just a single line.

it can simplify 

string SampleText;

if(Datetime.Now.Month == 12)

{

SampleText = "Christmas Month";

}

else

{

SampleText = "Some Other Month";

}

into

string SampleText = Datetime.Now.Month == 12 ? "Christmas Month" : "Some Other Month";

or much even this

string SampleText;

if(passedParameter != null)

{

SampleText = passedParameter;

}

else if (passedParameter1 != null)

{

SampleText = passedParameter1;

}

else if (passedParameter2 != null)

{

SampleText = passedParameter2;

}

else if (passedParameter3 != null)

{

SampleText = passedParameter3;

}

else

{

SampleText = string.Empty;

}

to simple

string SampleText = passedParameter ?? passedParameter1 ?? passedParameter2 ?? passedParameter3 ?? String.Empty;

and this is not limited to strings, it also applies to Objects.

More to share as we go to the world of coding (^-^)
